Abstract: The anisotropy of the conductivity and the shape of the I – V characteristics for a two-dimensional quantum superlattice with the nonharmonic electron dispersion law are investigated for different directions of the current and field applied to the structure relative to the superlattice axes. The anisotropy of the characteristics and the conditions for the occurrence of multivalue I – V characteristics in different current flow modes are discussed. It is shown that the deviation of the electron dispersion law in a two-dimensional quantum superlattice from the harmonic one in a strong dc electric field noticeably affects the shape of the I – V characteristic of a two-dimensional quantum superlattice. Several current peaks in a strong field are caused by both mixing of the current lines for directions orthogonal to the applied field and electron transport over Stark-ladder levels formed in different miniband valleys.
Keywords: two-dimensional superlattices, non-associative dispersion law, anisotropy, dc electric field, – characteristic, Stark states.
